Endometriosis

Effect of concomitant use of an antimycotic, an antibiotic, a spermicide or tampons on pharmacokinetics of anastrozole and levonorgestrel released from intra-vaginal ring

Trial purpose

To investigate the pharmacokinetic effect of a vaginally
administered antimycotic (miconazole), antibiotic
(clindamycin), spermicide (nonoxynol-9) or the
concomitant use of tampons during the use of an intravaginal
ring releasing anastrozole and levonorgestrel

Key Participants Requirements

Age

18 - 50 Years
  • - Healthy pre-menopausal female subject.
    - Age: 18 – 50 years (inclusive) at the first screening visit. For the subject > 45 years follicle stimulating hormone (FSH) will be investigated at the second screening visit to confirm the pre-menopausal status (FSH < 40 IU/L in serum).

    - Agreement to use adequate non-hormonal contraception.
    - Confirmation of the subject’s health insurance coverage prior to the first screening examination/visit.

  • - Incompletely cured pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal.
    - Thrombophlebitis, venous / arterial thromboembolic diseases (particularly deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction).
    - Presence or history of prodromata of thrombosis (e.g. transient ischemic attack, angina pectoris).
    - Known hypersensitivity to the study medications (active substances or excipients of the preparations).
    - Regular intake of medication other than hormonal contraceptives.
    - Use of systemic or topical medication or substances which oppose the study objectives or which might influence them within 4 weeks before first administration of the study medication,
    - Smoking of more than 10 cigarettes daily; if the subject is a smoker: subject is older than 35 years
    - Suspicion of or known current drug, medicine or alcohol abuse (including anabolics, high-dose vitamins).
    - Abnormal cervical smear
    - Previous ectopic pregnancy.
